SQL injection vulnerability in the submitSurvey function in controller.php in JQuarks4s (com_jquarks4s) component 1.0.0 for Joomla!, when magic_quotes_gpc is disabled, allows remote attackers to execute arbitrary SQL commands via the q parameter in a submitSurvey action to index.php.
Improper Neutralization of Special Elements used in an SQL Command The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
